Preview: Climate change takes centre stage in Under Thin Ice

There has been a lot of information, misinformation and confusion about climate change. Are the extremes in temperature, ferocious weather and melting ice the final warning before something truly horrible happens to the planet? I turned to “Under Thin Ice” for answers.

Airing this Friday as part of The Nature of Things, the doc—from Montreal’s Galafilm Productions—looks at the impact global warming has on polar life. Narrated by cinematographer and diver Jill Heinerth, who captured the underwater footage alongside Mario Cyr, “Under Thin Ice” begins by stressing the importance of the polar ice to the animals that live above and below its surface. With it disappearing at an alarming rate, Heinerth and Cyr head to Lancaster Sound for a dip. On the way, they reflect on eight-degree temperatures increasingly wider leads in the ice. And, once they arrive at camp, they discover their tents have flooded.

Stunning overhead shots of the sled journey, and surface and underwater footage of narwal, beluga and bowhead whales, polar bears, seals and microscopic animals show the unique and even alien world the Arctic is. And how quickly the ice in it is disappearing. If the current warming trend continues, Heinerth says, by 2040 there could be no sea ice on the entire Arctic Ocean during the summer, something unheard of until now.

“Under Thin Ice” airs as part of The Nature of Things on Friday at 9 p.m. on CBC and on CBC Gem.
